The PCR protocol that is currently used in laboratories was facilitated by the discovery of a bacterium called Thermus aquaticus in a hot spring inside Yellowstone National Park, Wyoming. This organism contains a heat-stable form of DNA polymerase known as Taq polymerase, which continues to function even after it has been heated to 95 degrees C. Why would such a heat-stable polymerase be beneficial in PCR

The correct answer is - Each cycle includes a "hot" denaturation phase (95C), which separates the hydrogen bonds that hold the strands of the template DNA together.

Explanation:

PCR is a polymerase chain reaction created by karry Mullis which is utilized to amplify a copy of DNA segments or a single copy of DNA or gene. The following are the steps involved in PCR reaction;

Denaturation: During this progression, the two-fold strand of DNA gets separated. The temperature required for this progression is 94 — 98 C.  

Annealing: during this progression, Template DNA and DNA primers get attached. The temperature required for this progression is 55 — 70 C  

Extension: During this progression, the polymerase includes the bases that are reciprocal to the template DNA strand. The temperature required for this progression is 65 — 72 C.  

At such high temperatures, DNA polymerase gets denatured. As it very well may be found in the above strides for the isolation of the DNA strand high temperature of 94 — 98 C Is utilized. Taq polymerase can withstand such high temperatures.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
